Poorly sorted vs well sorted sediment
Sorting describes the distribution of grain size of sediments, either in unconsolidated deposits or in sedimentary rocks. This should not be confused with crystallite size, which refers to the individual size of a crystal in a solid. Crystallite is the building block of a grain. Very poorly sorted indicates that the sediment sizes are mixed (large variance); whereas well sorted indicates that t… WebSedimentary rocks generally have porosities in the range of 10% to 30%, some of which may be secondary (fracture) porosity. The grain size, sorting, compaction, and degree of cementation of the rocks all influence primary porosity. For example, poorly sorted and well-cemented sandstone and well-compressed mudstone can have very low porosity.

WebSorting refers to the range of grain sizes in a sediment deposit or in a clastic sedimentary rock (Figure 5.3.5). Poorly sorted sediments contain a wide range of grain sizes. Deposits … WebApr 2, 2024 · Sorting, or separation of clasts into similar sizes, also happens during sediment transport. Sorting occurs because the size of grains that a medium of transport …
WebJan 15, 2024 · Sorting is the range of grain sizes that occurs in sedimentary materials. Well-sorted materials have grains of the same size, while poorly sorted materials have grains of many sizes. Permeability decreases as the degree of sorting varies from good to poor because small grains can fill the spaces between large grains. WebPermeability is a function of the size of pore openings. If sediments are well sorted, pore spaces are uniformly sized, thereby allowing for groundwater flow readily between …
